Any damage you take for the next 6 seconds, or when you next trigger the ability, will be stored. When this ends, you will deal 100% of the damage taken back at your target up to 10,000. In PvP there are diminishing returns on the damage stored as it increases.

When activated, it tracks damage taken from all sources for up to 6 seconds. After this time or when reactivated, the player attacks their target for 100% of the damage stored, with a damage cap of 10,000. Reprisal has significantly increased hit chance. The damage has diminishing returns during player killing.

Triggering the ability manually can be done outside of the global cooldown. Self-inflicted and both types of typeless damage will be tracked by Reprisal (e.g Vorago's Team Split mechanic, which deals hard typeless damage). For reasons unknown, it does not count the damage healed off of with Resonance (whereas Reflect will), so any hit that is mitigated by Resonance will only add one damage to Reprisal.

Reprisal is locked to the target it was initiated on, meaning that if a player uses Reprisal on one target and then begins attacking another while the original target is still alive, Reprisal will still damage the target it was initiated on.
